The aim of the game is to end up with no cards on the board. Each turn, one card is dealt from the pack of cards to the top of the board. For card removal the card on the top and the fourthmost card on the top are examined. If these cards are the same sort, the two cards between them can be removed. If these cards have the same value, the two cards between them and the cards themselves can be removed. After the pack of cards is empty, the card on the bottom can be dealt to the top and so forth. When no cards can be removed from the board at all, the game is lost.
